This invention relates to stoves, 'butl is more particularly concerned with ,broeder stoves of the wickless type. y i l Y Objects'of this linvention are to provide in connection with 4a brooder stove temperature controlled means for regulating the action or operation of the Iburner in such a manner that the temperature within the room in which the stove is positioned is maintained constant to provide a thermo,A

static device which is adaptedfto raise or lower the burner relatively to. the supply reservoir for varying the amount' of fuel supplied tothe burner; and to provide a brooderstove having the new and improved features of construction, arrangement and operation hereinafter described.

The invention is shown by way of illustration in the accompanying drawings, in which,--

Fig. 1 is a perspective view of the broeder stove; Fig. 2 is an elevation partly in section of the burner; and Fig. 3 is a vertical sectional view of the fuel supply reservoir.

The illustrated embodiment of the invention comprises a sheet metal U-shaped support 1 having` edge flanges 2 for securing the support in the desired position. Mounted on one end of the support 1 is a reservoir for oil or the fue.l, and in this instance the reservoir comprises a bowl 3 having a ring 4 provided with depending arms 5 which are pivoted at their lower ends to the upper portion of the support` 1. The ring 4 is adapted to receive and support an inverted jar 6 containing the oil or other fuel and formed on the jar 6 is a neck 7. It will readily be apparent that the height of liquid level in the bowl 3 is controlled by the neck 7. From the reservoir the liquid fuel flows through a pipe 8 which extends downwardly from the bowl 3 through an opening 9 in a support 1, then extends horizontally beneath the support 1 and upwardly through an opening 10 in the support, the end portion of the pipe being connected to the burner 11. The burner 11 may be. of any suitable form, but., in this instance is provided with an annular chamber 12 in which asbestos packing, or Y other similar substance, may be placed, and as will readily be understood, this substance is saturated with liquid fuel from the reservoir and ignited. Mounted in any suitable manner over the burner 11 is a frusto-conica lly shaped shadeor hood 13 which serves as a shie d for the burner flame.

,In accordance withthis invention, thermostatic means is provided for raising andl lowering theburner` 11. relatively to` the reservoir so that aV greater or less amount of fuel` is suppliedto the burner in accordance with the requirements of service. .It will.,`

of.course be understood that in the use of stoves of this character it. is'desired to maintain theteinperature within the Vroom approximatelyat a certain predetermined degree so that the chicks will not be injured as result-of too great or .toolow a temperature. V

For accomplishing this purpose, a lever 14 is pivoted intermediatey itsv ends to a bracket 15 which is supported on the top of the sheetnietalsupport 1. .TheY outer endl of the lever 14 engages the underside of the burner 11 and mounted on the inner end portion of the lever is a sliding weight 16 which serves as a counterbalance and may be adjusted to the. proper position. The outer end of the lever 14 is connected by means of a rodv17 to the pipe 8 as shown, and it will be seen that clock-wise movement of the lever 14 elevates the burner 11, and counter-clockwise movement of the lever lowers the burner, this lowering action being insured by means of the rod 17.

Suitably mounted on the support 1 is. a thermostatic plate 18 provided with an upstanding pin 19, and this plate may be of -V any suitable construction which is adapted to snap from one position to another at different predetermined temperatures. For eX- ample, this thermostat may be constructed to expand at a. certain predetermined high temperature and contract at a predetermined low temperature, or it may be so constructed as to change from a normally convex position to a concave position at the desired tem.- peratures. Thermostats of the above construction are well known in the art and may consist of two metals having different coefficients of expansion as to be actionable at the desired temperatures. 1n view of the fact that the construction of the thermostat forms no part of the epresent "invention, further description thereof is deemed unnecessary.

The action of the thermostat 18 is transmitted through apin 19 to a screw 20 in kthe lever 14 so that movement of the thermo# stat in one direction raises one end of the lever 14, which in Vturn elevates the burner 11 and pipe 8 to diminish or completely shut off the fuel supply from the reservoir. It

will be seen that adjustment of'the'screw 20k operates to regulate the movement of the burner 11. Connected to the lever 14 between the screw 20 and burner 11 is a screw 21 which is adapted to engage -the top 'ofy the support l, and this screw serves `to adjust the normal level of the fuel in the burner 11. p y Y When it is desired to discontinue the operation' of the stove, the lever 14mm] "be that numerous changes in details of con struction andarrangement may beefeetedv without departing from the spirit'of the invention, especially as defined in the appendedxclaims. A

What I claim is: 1. In a device of the class described, a burner, a fuel' supply'reservoir, rigid connection between said reservoir and burner, means for pivotally mounting said reservoir, a lever` adapted to engage the underside of said burner,means for pivoting said lever intermediatethejends thereof, a therinostatic device adapted to move said lever at different'V predetermined temperatures, adjustable means on said lever for varying the amount of oil normally'supplied to said burner, and an adjustable counter-balance on t-he opposite end of said lever.

2. In a device of the class described, av

burner, a fuel supply reservoir, rigid connection ybetween said' reservoir and burner, a lever adapted to engage the underside of said burner, means for pivoting said lever intermediate theends thereof, a thermostatic deviceadapted to move said lever atditferent predetermined' temperatures, adjustableV means on saidlever forivarying the amount of oil normally supplied to said burner, an adjustable counter-balance on the opposite end of said lever, and a catch adapted to en-` f gage the end of said'lever adjacent lsaid counter-balance for holding said burner in inoperative position. Y f

In testimony whereof I have hereunto signed my name to this specification.
